LED Displays: The Heart of Touch Monitors
LED (Light Emitting Diode) displays are a popular choice for touch monitors due to their vibrant colors, energy efficiency, and slim design. Understanding how LED displays work is essential for appreciating their role in touch monitor technology.
How LED Displays Work
LED displays operate by using an array of tiny light-emitting diodes to create images. These diodes emit light when an electric current passes through them, allowing for the production of bright and colorful visuals. The technology can be divided into two main categories: RGB (Red, Green, Blue) and monochrome displays.
RGB LED displays combine red, green, and blue diodes to create a full spectrum of colors. By adjusting the intensity of each color, these displays can produce millions of different hues. Monochrome displays, on the other hand, use a single color, typically green or amber, and are often found in simpler applications where color is not a priority.
